Barry McManus, who served for ten years as the CIA’s Chief Polygraph Examiner and Interrogator, is one of the world’s foremost authorities on “leakage” – which is the physiological response when you lie (sweaty palms, lack of eye contact etc.) Going further, he notes you have about 50 muscles in your face, and a few involuntarily contract when you are deliberately saying untruths. Also, for what it’s worth, your nose temperature rises.
So if you are worried your kids may start lying to you, you can either closely observe their facial features while interrogating them, or simply reinforce the supreme value of always telling the truth, of being honest, no matter what.

Here are 10 ways to teach your children to be honest.
Huddle up with your children tonight and say: “Honesty is always the best policy because ____.”
